To all whom it may concern.-

Be it known that I, JOSEPH M. IR ING, of Haverhill, county of Essex,State of Massachusetts, have invented an Improvement in OementingAttachments for Heeling Machines, of which the following description,"inconnection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

In attaching heels to shoes by the ordinary heel-nailing machine themain part of the heel is usually first secured to the shoe, the nailsbeing allowed to project slightly beyond the surface of the heel, andthen the top lift of the heel is spanked on so that the nails do notprotrude through the top lift. This means of securing the top lift israther insecure, and difficulty often arises from having 'the top liftcome off, so that it is practically necessary that the top lift becemented onto the heel as well as held on by the projecting nails.

The object of my invention is to provide an ordinary heel-nailingmachine with an automatic device for discharging measured quantities ofliquid cement upon theinner side of the top lift after it has beenplaced in position to be carried beneath the heel and before it issecured to the heel. Experience has shown that means for applying liquidcement which employ a sponge or brush through which the cement passesare wholly unsuited for this purpose, as the sponge or brush soonbecomes filled withthe solid matter which is in the cement, or becomesdried or hardened when not in use, so that the cement cannot passtherethrough with sufficient readiness.

I accomplish the object of my invention. above referred to and withoutemployinga.

sponge or brush in applying the cement by providing a tube in which thecement is contained under pressure, and at the extreme lower end ofwhich I providea valveof simple form adapted to be automatically openedupon the upward movement of the headblock and immediately closed, sothat only a limited quantity of cement is discharged therethrough, saidtube and valve being so located that the cement which is dischargedtherefrom drops directly upon the upper side of the top lift in themiddle thereof while it is held on the spanking-plate, the quantity ofcement being sufiicient to cause the same to be'spread over practicallythe entire surface of the lift when it is spanked onto the heel. Foramore definite understanding of my invention reference is now made to theaccompanying drawings, in which Figure 1 represents a front View, andFig. 2 a side view, of a portion of a heeling-machine of ordinary form,sufficient parts thereof being "illustrated to enable the operation ofthe attachment which comprises my invention to be understood. Fig. 3'isa plan'view of the table or bed of the machine with my attachmentapplied thereto. Fig. 4 isa perspective view of my attachment. Fig. 5 isa side view thereof, showing the valve in" open position; and Fig. 6'isan enlarged cross-section of the valve. i

As indicated in the drawings, the frame 1 of the machine is providedwith the usual head-block 2, which is guided to move lvertically in theframe in the ordinary manner. The jack 3 is arranged directly above thecentral portion of the head-block, as shown.

The spanking-plate5 ispivoted at 6 and is provided with a yoke4', and aspring-actuated holding-arm 40 is carried by said plate and holdsthe'heel against said yoke 4.. The plate 5 is also provided with a yoke7, against which the top lift is placed and held by thespring-actuatedarm 70. For convenience the yoke4 and arm 40 willbe'ter'med the heel-holder and theyoke 7 and arm'ZO the top-lift holder.Said plate 5 is also provided with a projecting portion 8, on the end ofwhich a socket orcup 12 is-provided, said projection and socketconstituting what I shall hereinafter 'refer to as an engaging device.

A lever 9 is pivoted to a bracket 10, the latter being firmly secured tothe'frame of the machine. A rod 11 is pivoted to the lefthand end of thelever 9and hasa fiat side atits upper end which is normally held againstthe side of-a bracket 90 on said lever 9 by means of a, spring 91, sothat the lower end of rod 11 is normally held directly above said socketwhen said plate 5 is in the right-hand or full-line position shown inFig. 3, said rod 11 being free to swing to the right and its lower endbeing normally suspended above the end of the cup 12. A spring 13 isconnected to the lever 9 and acts to draw the right-hand end of lever 9against a stop 130 on the frame.

A liquid-cement-eontaining tank 1a is arranged above the main portion ofthe machine and is provided with a discharge-pipe 15, which leadsdownwardly and is rigidly secured to a bracket 16. Said pipe 15 ispreferably of metal, particularly at its lower end, so that said lowerportion may be held rigidly. A valve 17 is arranged at the extreme lowerend of said pipe, said valve being preterably of the ordinaryturning-plug form, as shown in Fig. 6, and having a lever 18 securedthereto. A spring 19 is secured to the outer end of said lever and tothe bracket 16 and acts to hold said valve 17 in its closed position.

A flat-sided arm 20 is pivotally connected at 21 to the lever 18 andpasses through a slot 22 in the bracket 16, (see Figs. 3 and 4,) so thatit may swing toward the front of the machine. Said arm 20 is providedwith a shoulder 24 at its upper end, which is adapted to engage theunder side of the lever 9 at its right-hand end, and a spring 23 acts todraw the rear edge of said arm against said lever.

Said arm 20 isalso provided with a curved portion 25, which in certainpositions is adapted to engage a trip device or plate 26, adjustablysecured to the upper side of the bracket 16.

Having now described the general construction of my attachment, theoperation thereof may be described as follows: The shoe is placed uponthe jack 3, and the heel and top lift, which are to be attached thereto,are placed in the heel-holder 4E 40 and top'lift holder 7 70,respectively, the plate 5 then being in the right-hand position, (shownin full lines in Fig. 3,) so that the heel is held directly beneath thejack, and the lift is held at one side thereof. The head-block 2 is thenforced upwardly, and the nails carried thereby are driven through theheel, attaching the heel to the shoe. As the block 2 is moved upwardlythe plate 5 is carried with it, and its projecting portion 8 will engagethe lower end of the rod 11, said rod passing into the cup 12 of saidprojecting portion. This will cause the right-hand end of the lever 9 toswing downwardly, forcing down the arm 20 and swinging the handle 18,which is connected to the valve 17, to the position shown in Fig. 1,opening the valve and discharging a quantity of cement upon the toplift, which is in position directly beneath it. As the table is liftedthe lever 9 will continueto be swung, as just described; but as soon asthe arm 20 is pressed downwardly a short distance its curved portion 25will be engaged by the plate 26, and said arm will be swung forwardly,as shown in Fig. #1, so that its shoulder 21 will become disengaged fromthe lever 9, and the spring 19 will throw said arm and the handle 18upwardly, closing the valve. The parts are adjusted so that the valvebegins to close before it is fully opened, the extent to which it isopened depending on the adjustment of plate 26, so that a quantity ofcement is discharged upon the top lift, which is always practicallyconstant, the valve being opened the same distance and for the samelength of time each time it is opened. Vhen the block 2 again descendsto its normal position, the lever 9 will also return to its normalposition, and the spring 23 will swing the arm back to the positionshown in Figs. 2 and 4, so that it will be in position to be engaged bythe lever 9 when the rod 11 is again lifted. Before or as the head-blockstarts to move upwardly to spank on the top lift the plate 5 is swung tothe dotted position shown in Fig.6, so that the lift is carried directlybeneath the heel. When plate 5 is moved to said dotted position, theengaging devices 8 and 12 thereof will be swung to one side of the rod11, so that on this second upward movement of the block and plate theparts connected to the cement-supplying valve 17 will not be moved. Thepressure which is applied to the top lift in spanking it onto the heelwill cause the cement which has previously been discharged thereon tospread over the surface of the connected parts, thoroughly cementing oneto the other. It will be observed that this operation is purelyautomatic, and the cement will be applied without trouble or attentionon the part of the operator, it simply being necessary to supply thetank 14: with cement at properintervals.

The valve 17 is of such construction that its effectiveness of operationwill not be impaired by the continued fiow of cement through it, so thatpractically a measured quantity of cement will always be discharged uponthe top lift for the same adjustment of the plate 26, the extent towhich the valve is opened, and consequently the quantity of cementdischarged, being varied by adjusting said plate 26.

While I have illustrated a preferable form of apparatus for applying thecement to the top lift, yet other forms may be satisfactorily employedin a machine of this general character without departing from the spiritand scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
